Wherein, correction value calculating part 136 and drive control part 137 are equivalent to " the control changing unit " controlled according to the activity change air conditioning of being calculated by activity calculating section 135.

The handling process of<control module >

Then, with reference to Fig. 5, use Fig. 4 that the summary of a series of processing that control module 130 is carried out is described.Fig. 4 means the flow chart of the flow process of the processing that control module carries out.

In the step S101 of Fig. 4, control module 130 is set as 1(n=1 by the value of n), be saved in memory cell 140.Wherein, n is the value of being counted for the number of times to calculating above-mentioned amount of movement and activity.

In the step S102 of Fig. 4, control module 130 judges whether start to process rear (that is, from the moment of START) has passed through stipulated time Δ t1.Wherein, stipulated time Δ t1 is predefined time (for example counting msec), is stored in memory cell 140.

In the situation that after starting to process through stipulated time Δ t1 (S102 → Yes), the processing of control module 130 advances to step S103.On the other hand, after starting to process, also do not pass through in the situation of stipulated time Δ t1 (S102 → NO), control module 130 carries out the processing of step S102 repeatedly.

The input that in step S103, control module 130 is accepted from the image information of taking unit 110, be saved in memory cell 140 by this image information.

For example, with taking unit 110, take the image information corresponding with the such RGB image shown in Fig. 5 (a), input to the body detecting part 131 of control module 130 by the A/D converter section.

Then, in the step S104 of Fig. 4, control module 130 is read image information from memory cell 140, carries out human detection and processes.Then, control module 130 makes the human body label value of the information of human body image supplementary features (that is, human body information) and identification sign as each human body associated, is saved to memory cell 140(with reference to Fig. 9 (a)).

In addition, while carrying out the human detection processing, control module 130 is processed and is compared with face detection described later, with the human body of the people in larger pixel separation sensing chamber.Thus, can alleviate control module 130 and carry out the processing load of human detection while processing.

For example, whole body indoor people A, B, the C that unit 110 photographs that be taken roughly in Fig. 5 (a), detect as symbol A1, B1, C1(with reference to Fig. 5 (b) by body detecting part 131) bianry image that means.On the other hand, for the part that health is only arranged (head, shoulder), be taken indoor people D(that unit 110 photographs with reference to Fig. 5 (a)), do not detect human body (with reference to Fig. 5 (b)).

Then, in the step S105 of Fig. 4, control module 130 is read image information from memory cell 140, carries out face detection and processes.Then, control module 130 makes the information of face image supplementary features (being facial information) associated with face's label value of identification sign as each face, is saved in memory cell 140(with reference to Fig. 9 (b)).

For example, indoor people A, B, the D that unit 110 photographs that be taken of face, detect as symbol A2, B2, D2(with reference to Fig. 5 (c) by face detection section 132 in Fig. 5 (a)) shown in face image.On the other hand, for towards rearward indoor people C(with reference to Fig. 5 (a)), do not detect face (with reference to the symbol C1 of Fig. 5 (c)).

Then, in the step S106 of Fig. 4,130 pairs of control modules process by human detection human body informations that (S104) obtain and processed above-mentioned each label value of facial information use that (S105) obtain by face detection associated.That is, the center of the head of each human body process detected by human detection and the center of being processed the face of detecting by face detection be predetermined distance with in interior situation, to this human body, with face, use label value associated.

Thus, can suitably judge by human detection and process the human body detected and the whether corresponding same indoor people of face who is detected by the face detection processing.

Then, in the step S107 of Fig. 4, control module 130 calculates by each indoor people's of above-mentioned label value association amount of movement.Then, control module 130, by the amount of movement calculated, is saved in memory cell 140 associatedly with label value.

In example shown in Fig. 5, for indoor people A, the B that detect face, D(with reference to Fig. 5 (a)), use with face image A2, B2, D2(with reference to Fig. 5 (c)) corresponding facial information calculating amount of movement.

On the other hand, although do not detect face, for the indoor people C(that detects human body with reference to Fig. 5 (a)), use with human body image C1(with reference to Fig. 5 (c)) corresponding human body information calculating amount of movement.

In step S108, control module 130 calculates by each indoor people's of above-mentioned label value association activity.

Then, control module 130 by the activity calculated associated with label value be saved in memory cell 140.Wherein, in the situation that the value of said n is more than 2, control module 130 successively adds up (calculate and) by each the indoor people by the label value association to activity.

In step S 109, control module 130 judges whether the value of n equals N.Wherein, N is predefined natural number, is stored in memory cell 140.

In the situation that the value of n equals N (S109 → Yes), the processing of control module 130 advances to step S111.On the other hand, in the situation that the value of n is not equal to N (S109 → No), the processing of control module 130 advances to step S110.

In step S109, the value of 130 couples of n of control module adds 1.That is, make the value " 1 " of the n that sets in step S101 add 1 and become " 2 ".

Like this, control module is carried out the processing of step S102～108 N time repeatedly.

In step S111, control module 130 calculates the correction value that air conditioning is controlled.That is, control module 130 each indoor people's based on by the label value association activity (activity during time Δ t1 * N), calculate the correction value that air conditioning is controlled.

Wherein, the calculating of this correction value can be used the distribution (distribution of left field and right side area etc.) of indoor activity, or uses specific indoor people's position and activity.

In step S112, control module 130 is used the correction value calculated in step S111 to carry out the change processing that air conditioning is controlled.That is, the drive control part 137 of control module 130, except above-mentioned remote controller signal and sensor signal, also used the correction value of calculating based on activity meter to carry out the change processing that air conditioning is controlled.

<each details of processing >

(1. human detection is processed)

Fig. 6 means the flow chart of the flow process that human detection is processed.

In step S201, control module 130 is carried out binary conversion treatment.That is, control module 130, read the image information of inputting from taking unit 110 by A/D converter 120 from memory cell 140, by the RGB image transitions, be bianry image.Wherein, this binary conversion treatment is for example cut apart the RGB image by predefined a plurality of pixel separation, uses the accumulative total of for example, in each zone (zone of 5 * 5 pixels) brightness value to carry out binaryzation.Thus, can carry out human body identification and reduce operand with larger pixel separation, can alleviate the load of control module 130 and make to process high speed.

In step S202, control module 130 is used the information of the bianry image of being obtained by above-mentioned binary conversion treatment to detect head zone.That is, control module 130 is from 0 or 1 the distribution of investigating from the top down horizontal line of binary image, based on this distribution according to whether existing the part of the shape (circular) that is equivalent to head image to detect head zone.

In step S203, control module 130 is used the information of bianry image to detect leg area.For example, whether control module 130, from 0 or 1 the distribution of investigating from bottom to top horizontal line of binary image, exists shank to detect leg area according to the below of the head of obtaining in step S202.

In step S204, control module 130 calculates the human body center.For example, the position of the leg area obtained in the head zone of control module 130 based on obtaining in step S202 and step S203, the position, center (or center of gravity) of calculating human body is the human body center.In addition, the information at this human body center, be obtained as the positional information (lengthwise position, lateral attitude) of determining the pixel of stipulating.

In step S205, control module 130 extracts shoulder regions.For example, control module 130 for example the upper end by zone from the head to the pixel count of the lower end of leg area, whether the pixel value of position of the shoulder regions that head zone and leg area infer as benchmark of take be 1, carries out the extraction process of shoulder regions.

In step S206, control module 130 makes the information that obtains in the processing of step S201～S205 associated with the label value for identifying indoor people, as human body information, is saved in memory cell 140.

By such processing, can obtain the relevant human body information of human body image shown in Fig. 5 (b).

(2. face detection is processed)

Fig. 7 means the flow chart of the flow process that face detection is processed.

In step S301, control module 130 is carried out the filtering processing and is removed denoising from image information.That is, control module 130 is read the information of the image about being photographed by shooting unit 110 from memory cell 140, for example, uses wavelet transformation to remove denoising from the RGB image information.

Detect face area at step S302 control module 130.For example, control module 130 is obtained color histogram for above-mentioned RGB image information of having removed noise, will detect as face area with the zone of difference below setting of the color histogram of pre-stored face image in memory cell 140.

In step S303, control module 130 detects mouth area.That is, control module 130, by the detected face area of step S202, covers the plate image information with the pre-stored oral area in memory cell 140 and compares, and detects mouth area.

In step S304, control module 130 detects ocular.That is, control module 130, by the detected face area of step S202, covers the plate image information with the pre-stored eye in memory cell 140 and compares, and detects ocular.

In step S305, control module 130 makes the information obtained in the processing of step S301～S304, associated with the label value for identifying indoor people, as facial information, stores memory cell 140(into reference to Fig. 9 (b)).

By such processing, can obtain the facial information about the face image shown in Fig. 5 (c).

(association of 3. being undertaken by label value)

Then, use Fig. 8 that the association process of the use label value that control module 130 is carried out is described.

In the step S401 of Fig. 8, control module 130 is set as 1(k=1 by the value of k), store memory cell 140 into.Wherein, k is while carrying out processing the processing of (with reference to the S104 of Fig. 4) detected M human body about human detection, successively the value of increase.

In step S402, control module 130 judges whether distance L is predetermined distance L ₀below.In addition, distance L refers to the head center of the specific human body image corresponding with the value of above-mentioned k and is processed the distance (pixel count) between the face center of detecting by face detection.That is, control module 130 determines whether to exist and is positioned at the head center predetermined distance L apart from human body image ₀with interior face area.

There is L≤L ₀the situation of face area under (S402 → Yes), the processing of control module 130 advances to step S403.On the other hand, there do not is L≤L ₀the situation of face area under (S402 → No), the processing of control module 130 advances to step S404.

The label value of the face image that in step S403, control module 130 will be corresponding with k=1 (face's label value), as this, indoor people's label value is saved in memory cell 140.Thus, can be by with label value is associated, guaranteeing human detection and face detection detected indoor people's homogeneity respectively.In addition, for the indoor people who is identified by human detection and face detection both sides, when calculating amount of movement described later, can preferentially use face image.

In step S404, the label value of control module 130 using the human body label value as indoor people is saved in memory cell 140.Thus, in the situation that can not detect face, also can calculate amount of movement by end user's volume image.

Fig. 9 (a) means the table of the corresponding relation of the indoor person to person's body label value that is detected human body.For example, during for the indoor people C acquisitor volume image information shown in Fig. 5 (a) (with reference to the C1 of Fig. 5 (b)), control module 130 makes this image information be saved in memory cell 140 in above-mentioned human detection is processed associatedly with human body label value " bbbC ".

Wherein, because the indoor people D for shown in Fig. 5 (a) does not detect human body, so not additional human body label value (with reference to Fig. 9 (a)).

Fig. 9 (b) means the table of the corresponding relation of the indoor people that is detected face and face's label value.For example, while for the indoor people D shown in Fig. 5 (b), obtaining facial information (with reference to the D2 of Fig. 5 (c)), control module 130 makes this facial information be saved in memory cell 140 in above-mentioned face detection is processed associatedly with face label value " fffD ".

Wherein, because the indoor people C for shown in Fig. 5 (a) does not detect face, so not additional face's label value (with reference to Fig. 9 (b)).

Fig. 9 (c) means the table of the corresponding relation of indoor people and label value.For example, the human body image A1(of indoor people A is with reference to Fig. 5 (b)) head center and face image A2(with reference to Fig. 5 (c)) the face center between distance L be predetermined distance L ₀with (S402 → Yes of Fig. 8) in interior situation, it is images of same person that control module 130 is identified as them.Then, adopt " fffA " conduct people additional label value (with reference to Fig. 9 (c)) indoor to this as face's label value.

That is, control module 130, about the computing of amount of movement described later, is used the image information A2(associated with the label value fffA of face with reference to Fig. 5 (c)).Thus, amount of movement and the activity of the people in counting chamber exactly.

On the other hand, as shown in Fig. 5 (a), (c), the indoor people C about back to taking unit 110, do not detect face.(S402 → No of Fig. 8) under these circumstances, control module 130 adopts " bbbC " conduct label value (with reference to Fig. 9 (c)) additional to indoor people C as the human body label value.

That is, control module 130, for the computing of aftermentioned amount of movement, is used the image information C1(associated with human body label value bbbC with reference to Fig. 5 (c)).Thus, in the situation that indoor people also can calculate this indoor people's activity back to the situation of taking unit 110 or because backlight can not detect face.

Again returning to Fig. 8 goes on to say.

In step S405, control module 130 takes a decision as to whether k=M.Wherein, the value of M is detected indoor people's quantity, M=4 in the example shown in Fig. 5 (b).

In the situation that k=M (S405 → Yes), control module 130 finishes to use the association process of label value, advances to the calculating (with reference to the step S107 of Fig. 4) of amount of movement.On the other hand, if not k=M(S405 → No), the processing of control module 130 advances to step S406.

At step S406, the value of 130 couples of k of control module adds 1, returns to the processing of step S402.

Like this, control module 130, make the human body image information homogeneity ground of guaranteeing indoor people associated with face image by label value, preferentially adopts face image information to calculate the object (with reference to Fig. 5 (c), Fig. 9 (c)) of processing as activity.In addition, for the information of failing to detect face image, adopt human body image information to calculate the object (with reference to Fig. 5 (c), Fig. 9 (c)) of processing as activity.

Wherein, above-mentioned processing by per stipulated time Δ t1(with reference to Fig. 4) repeatedly carry out, be also to exist some moment to use face image in same indoor people's situation, other use the situation of human body information constantly.Like this, the homogeneity ground switching by guaranteeing indoor people is as the kind of the image of processing object, can with indoor people independently follow the trail of each indoor people towards the irradiating state with light.

(the 3. computing of amount of movement)

Then, with reference to Figure 11, use Figure 10 that the amount of movement computing that control module 130 is carried out is described.

In step S501, control module 130 calculates the transverse width P of the picture of the face on the shooting face p that takes unit 110 ₂(with reference to Figure 11 (b)).Wherein, about detecting human body, still do not detect the indoor people of face, calculate the transverse width of the head of the human body picture on shooting face p.

In addition, the transverse width P of the picture of face ₂the transverse width that the horizontal maximum pixel number of picture that can be by face is multiplied by each pixel calculates.

At step S502, control module 130 is used the variable quantity of the center of the face's (or head) on shooting face p, the amount of movement Δ X on the left and right above-below direction of the people in counting chamber.

For example, consider that indoor people moves (the Δ X that moves right, to front side shifting Δ Y) from the state shown in Figure 11 (a) (from taking unit 110) front to the right, becomes the situation of the state of Figure 11 (b).Amount of movement Δ X now can be used (formula 1) of following expression to calculate.

Wherein, in (formula 1), symbol H is the transverse width of face's (or head) of indoor people, as the setting pre-save in memory cell 140.In addition, symbol X ₁the center of the picture of the face before moving, symbol X ₂it is the center of the picture of the face after moving.In addition, the calculating that also can use the same method of the amount of movement on above-below direction.

$\mathrm{\&Delta;X}=\frac{H}{P_2}\left|x_2{x}_1\right|$ (formula 1)

Then, in the step S503 of Figure 10, control module 130 is used the variable quantity of the transverse width of the face's (or head) on shooting face p, by the amount of movement Δ Y of people on depth direction in (formula 2) counting chamber shown below.

Wherein, symbol D1 is indoor people from the mobile distance to camera lens g in (formula 2), symbol D ₂it is indoor people from the movement distance to camera lens g.In addition, symbol P1 is the transverse width of the picture of the face of shooting face p before moving, symbol P ₂it is the transverse width of the picture of the face of shooting face p after moving.In addition, symbol F is from camera lens g to the distance of taking face p.

$\mathrm{\&Delta;Y}=|D_2-{\mathrm{<figure-callout\; id="1"\; label="D"\; filenames="HDA00002053913100041.png,HDA00002053913100071.png"\; state="\{\{state\}\}">D</figure-callout>}}_1|=|\frac{1}{P_2}-\frac{1}{{\mathrm{<figure-callout\; id="1"\; label="P"\; filenames="HDA00002053913100041.png,HDA00002053913100071.png"\; state="\{\{state\}\}">P</figure-callout>}}_1}|\mathrm{HF}$ (formula 2)

Then, in the step S504 of Figure 10, control module 130 is used the amount of movement Δ X of left and right directions and the amount of movement Δ Y of depth direction, by the actual amount of movement Δ D of the people in (formula 3) counting chamber shown below.

$\mathrm{\&Delta;D}=\sqrt{{\mathrm{\&Delta;X}}^2+{\mathrm{\&Delta;Y}}^2}$ (formula 3)

Like this, the amount of movement of the amount of movement of control module 130 based on the left and right above-below direction and depth direction calculates the S102 of afore mentioned rules time Δ t1(with reference to Fig. 4) indoor people's amount of movement Δ D.Thereby, can calculate exactly each indoor people's amount of movement.

Then, in step S505, control module 130 makes the indoor people's that calculates the amount of movement Δ D people's indoor with this label value store memory cell 140 into associatedly.

, use Figure 12, Figure 13 herein, illustrate that per stipulated time Δ t1(of the people that each is indoor is with reference to Fig. 4) the calculating of amount of movement.Wherein,, establish stipulated time Δ t1=1sec herein.

For example, at 9: 15: 00 constantly, take unit 110 and taken the image shown in Figure 12 (a), at 9: 15: 01 constantly, taken the image shown in Figure 12 (b).In Figure 12 (a) back to the indoor people C that takes unit 110, in Figure 12 (b) back to taking unit 110.In addition, indoor people A is close to taking unit 110.

Control module 130, calculating from 9: 15: 00 constantly to constantly between 9: 15: 01 during the amount of movement of indoor people A, position based on each face image of Figure 12 (a) and (b) and big or small change calculations go out amount of movement 7.259(with reference to Figure 13), be saved in memory cell 140(with reference to Figure 13) associatedly with label value NNNA.

In addition, at 9: 15: 02 constantly, take unit 110 and taken the image shown in Figure 12 (c), at 9: 15: 03 constantly, taken the image shown in Figure 12 (d).Wherein, in Figure 12 (c) in the face of taking the indoor people B of unit 110, in Figure 12 (d) back to taking unit 110.In addition, the indoor people D do not photographed in Figure 12 (c) is photographed in Figure 12 (d).

Control module 130 calculates as described below from 9: 15: 02 constantly the amount of movement of indoor people B between 9: 15: 03 extremely constantly.; position and the size of the head of the human body image of the position of the face image of control module 130 based on Figure 12 (c) and size, Figure 12 (d); calculate the amount of movement 1.268(of indoor people B with reference to Figure 13), be saved in memory cell 140(with reference to Figure 13) associatedly with label value NNNB.

Like this, the position of the indoor people of control module 130 based on changing through ground in time face and variation or the position of head and the change calculations amount of movement of size (transverse width) of size (transverse width) are saved in memory cell 140 associatedly with label value.

(the 4. computing of activity)

Figure 14 means the figure of the relation of indoor people's the amount of movement of per stipulated time and activity.

During control module 130 computational activity amount, successively calculate above-mentioned per stipulated time Δ t1(with reference to Fig. 4) amount of movement Δ D and accumulative total, the computational rules time, Δ t1 * N(was with reference to Fig. 4) in the total amount of movement.

In addition, with the amount of movement along with per stipulated time Δ t1 * N, increase, activity is larger mode also, and information pre-save that will be suitable with the figure of Figure 14 is to memory cell 140.

Control module 130 calculates above-mentioned amount of movement, calculates the activity corresponding with this amount of movement, is saved in memory cell 140 associatedly with above-mentioned label value.

(the 5. computing of correction value)

Then, as an example, the aggregate value of using detected each indoor people's activity during Δ t1 * N at the appointed time is described, calculates the situation of correction value of the design temperature of air conditioner A.

Figure 15 (a) and (b) mean the figure of relation of the correction value of activity and design temperature.Control module 130, according to the computational methods of the operation mode that receives and be kept at memory cell 140 from remote controller Re (for blowdown firing/warming operation) switching correction value.

[computing of the correction value during 5-1. cooling]

That is, in the situation that during the cooling shown in Figure 15 (a), control module 130 more reduces the correction value of design temperature when the activity calculated is larger.Herein, " design temperature " refers to the design temperature information and the above-mentioned activity that use from remote controller Re input and calculates the also value of driven control part 137 references by control module 130.

Wherein, in the situation that, in the scope that activity is not enough W1 more than 0, unmanned possibility is higher, so be set as making the correction value of design temperature higher.

[computing of the correction value during 5-2. heating]

Control module 130 during this external heating is in the situation that the activity calculated is not enough W1 more than 0, increases the correction value T8(of design temperature<0) absolute value.That is,, in the situation that activity is very little, control module 130 is judged indoor nobody, reduces design temperature in order to reduce power consumption.

Wherein, the above-mentioned indoor the judgement whether people is arranged, preferably not only consider activity, also considers whether body detecting part 131 or face detection section 132 detect the indoor people of having.

In addition, in the above zone of activity W1, control module 130 more increases the absolute value (reducing design temperature) of correction value (<0) when the value of activity is larger.

Like this, can be applicable to the air conditioning of indoor activity, and reduce power consumption.In addition, the activity by the people indoor more reduces design temperature when larger, and comfortableness air conditioner A preferably can be provided.

(change that 6. air conditioning is controlled is processed)

[1. with the corresponding wind direction of the distribution of activity, controlling]

Figure 16 means the flow chart of the flow process of the change processing that air conditioning is controlled.Wherein, in Figure 16, as an example, the situation that decision to which direction in indoor left field, middle section, right side area is blown when warming operation is described.

In step S601, control module 130 judges that whether activity calculate to process the activity that calculates as more than setting W.Wherein, setting W is the value of predefined activity.In the situation that activity is (S601 → Yes) more than setting W, the processing of control module 130 advances to step S602.On the other hand, in the situation that the not enough setting W (S601 → No) of activity, the processing of control module 130 advances to step S606.

In step S602, control module 130 makes design temperature reduce setting Δ T.For example, in the situation that, in the scope of the activity not enough W4 more than the W3 shown in Figure 15 (b) during warming operation, control module 130 adds correction value T7(<0 by design temperature), design temperature is reduced | T7|(=Δ T).

In step S603, control module 130 judges that whether the difference of the activity that left and right is regional is as more than Δ W.Wherein, the value of above-mentioned Δ W is preset and is kept in memory cell 140.

Wherein, the activity used in above-mentioned determination processing, be the aggregate value of the aggregate value of activity all the time of the indoor people in indoor left field and the indoor people's in indoor right side area activity all the time.

In the situation that the difference of the activity in zone, left and right is (S603 → Yes) more than Δ W, the processing of control module 130 advances to step S604.On the other hand, in the situation that the not enough Δ W of the difference of the activity in zone, left and right (S603 → No), the processing of control module 130 advances to step S605.

In step S604, control module 130, to activity, less zone (for example right side area) is carried design temperature is carried out to revised warm braw.

In step S605, control module 130, the central authorities' conveying in air conditioning chamber is carried out revised warm braw to design temperature.

For example, in the situation that be arranged on right side from taking unit 110 indoor sets 100, think, near the right flank of indoor set 100, wall is arranged.Thereby, the left side air-supply of indoor set 100 is not set by deflection, can carry out more efficiently air conditioning.

In addition, in the second embodiment, the user profile that the user based on about logining has been described is carried out the situation that the change of air conditioning control is processed, and then, can also learn each user's action model, the air conditioning of carrying out based on this learning outcome is controlled.

For example, can there is unit (not shown), this unit is according to save as each user of user profile in memory cell (the first memory cell) 140, make the user Nei position, air conditioning chamber with comprise that the design temperature of user when indoor and the air-conditioning information association ground of wind direction are learnt, generation action model information.

In this case, be saved in memory cell 140 the action model information that unit will be learnt and above-mentioned user information correlation.Then, control module 130, in the situation that face detection identifies the user in processing, is read the action model information corresponding with this user from memory cell 140, carries out air conditioning based on this action pattern information and controls.

For example, learning with in the situation that the cold wind that makes when the blowdown firing to carry from indoor set 100 does not directly blow to specific user's mode takes action, unit by this learning outcome (action model information) and user information correlation be saved in memory cell 140.Then, control module 130 is in the situation that face detection detects this user in processing, read the action model information corresponding with this user from memory cell 140, thus control left and right wind direction board 104 and up-down wind direction board 105 towards making cold wind directly not blow to this user.

Wherein, the study that above-mentioned unit is carried out is processed, and for example can use the layering neutral net.

In addition, in the respective embodiments described above, detect in same indoor people's human body and the both sides' of face situation, preferentially use face image to calculate amount of movement, but be not limited to this.That is, under these circumstances, also preferentially end user's volume image calculates amount of movement.

In addition, in the respective embodiments described above, illustrated that taking unit 110 arranges the situation of in the bottom of the left and right directions central authorities of the front panel 106 of indoor set 100, but be not limited to this.For example, also the shooting unit can be arranged on to right side or the left side of front panel 106.

In addition, plate 106 arranges a plurality of shootings unit in front.

In addition, take unit 110 and also can there is driver element (not shown).For example, take unit 110 and be connected with the axle of stepper motor as driver element, reciprocal in the scope of the angle that operates at regulation by motor.In this case, each zone that is divided into a plurality of zones in the scope of motor for the angle to by regulation is taken and stops, and after shooting, in order to make to take unit 110, towards next zone, restarts running.Wherein, with the speed of the driving of taking unit 110, compare, take in abundant short situation of required time, stepper motor also can continuous operation.

Thus, can use narrow viewing angle and cheap shooting unit 110.In addition, the images such as change noise in each regional illumination and brightness ground is removed by coordinating, face detection, human detection are processed, and can carry out inferring of face detection and human detection, position based on them and activity with higher precision.And then the cost that can avoid the shooting unit 110 because loading a plurality of narrow viewing angle cheapnesss to cause improves, avoids because guaranteeing the maximization that space causes indoor set that arranges of a plurality of shootings unit 110.

In addition, the respective embodiments described above and variation can appropriate combination.For example, can be by the second embodiment and the combination of the 3rd embodiment, the air conditioning of carrying out based on user profile and room layout is controlled.
